Logic Self-Reporting Metamaterials
Project description
Within the interdisciplinary project Logic Self-Reporting Metamaterials, I investigate the potential of fruit peel as a model for energy dissipation in adaptive composites. In order to study the dissipative and ripening processes in fruit peels, I employ mechanical tests, microscopy and micro-computed tomography to analyse the functional morphology of peels.
Project outcomes
In my project, I investigated the damping and material properties of various citrus fruit peels. The focus was particularly on the biomechanical and functional morphological properties of the fruit peel. As part of my work, I was able to show that not only the pomelo peel has excellent material and structural properties, but that a variety of citrus fruit peels have promising capabilities. It was possible to determine material characteristics such as Poisson's ratios (transverse contraction ratios) for various peels and to visualize the peel structures. In follow-up projects, the knowledge gained must now be abstracted using simulations and mathematical models and then applied in initial demonstrators. In this way, interdisciplinary and cross-area collaboration can ultimately lay the foundation for a genuine, bio-inspired livMatS damping material.
